Really interesting #neuroscience preprint from researchers at #Brandeis on characterising #neural activity in shared communication #subspaces between the #hippocampus and the #prefrontalcortex. I found it particularly intriguing that theta power appeared to decrease subspace dimensions and increase subspace predictability, while theta #coherence had much less of an effect. https://www.biorxiv.org/content/10.1101/2024.07.08.601617v1
